@Lizzipa .........
You may be right. Your comment reminded me that I killed a santolina several years back by pruning it too hard.
I saved all of the plant material I cut off to use for kindling next year once it has dried out. In the worst case ... if they don't come back ... I'll just yank them out and cut that wood for kindling, too, and plant something else in that bed. The bed is prepared, so I won't have to do that work twice.
Smiles,
Lyn
